Did Star Wars Help End the Cold War? Soviet Response to the SDI Program

The Strategic Defense Initiative (SDI), also known as the
Star Wars program, is most likely the most controversial project of the cold
war. Initiated by the United States in 1983, at the height of the cold war
tensions, as a research program aimed at development of a range of advanced
missile defense technologies, SDI had significant impact on the U.S.-Soviet
relations and undeniably played a significant role in the events that led to
the end of the cold war nuclear confrontation.[1] The
exact nature of that role, however, is still open to a debate.

According to one point of view, SDI was a key element in
the U.S. strategy to curb the Soviet military buildup of the 1970s, which eventually
led to the Soviet Union defeat in the cold war.[2] It
is often stated that the Star Wars program confronted the Soviet Union with the
prospect of a strategic competition in a new area, a one that would concentrate
on the technologies in which the United States had advantage. In a variation of
this argument, the SDI program made the Soviet Union realize that its economic
and social system can not sustain the technological arms race with the United
States, forcing the Soviet leadership to seek concessions that eventually accept
defeat.

A different view suggests that the influence of the Star
Wars program on the Soviet policies was much more limited and the developments
that resulted in the end of the cold war and subsequent collapse of the Soviet
system were results of its internal evolution. Even though U.S. policies
influenced the developments in the Soviet Union, they did not cause them.[3]

Statements and recollections of the Soviet participants of
the events of that time have been quite contradictory, complicating the matter.
On the one hand, the Soviet officials usually insist that they realized the
limited potential of the Star Wars program very early on and that SDI never forced
the Soviet Union to change its policies or negotiating positions. At the same
time, they admit that the program caused serious concerns to the Soviet
leadership.[4]

The policies of the Soviet Union at the time also indicate
that it was concerned about the SDI program. For most of the 1980s missile
defense and space remained among the most contentious issues at the U.S.-Soviet
arms control negotiations. The Soviet Union made the SDI program one of the
central issues at the summit meetings in Geneva in 1985 and in Reykjavik in
1986. In Reykjavik, the Soviet Union offered far reaching concessions on
offensive weapons, but then withdrew them when the United States refused to
limit its SDI program. This move has been often interpreted as a Soviet attempt
to trade its offensive weapons for the SDI program, indicating the very high
value that the Soviet Union assigned to it. Overall, the Soviet behavior was
not inconsistent with that of a country concerned about technological
superiority of its adversary, lending support to the theories that claim that
SDI was a political success.

One of the reasons this controversy persists is that until
very recently there has been little reliable information about the nature of
the Soviet response to the Star Wars program. While most indicators strongly
suggested that "as a measure to stress the Soviet economy and affect Soviet
policy, SDI never got off the ground," in the absence of documentary evidence
it was not entirely clear why the Soviet Union paid so much attention to the
U.S. missile defense efforts and what was the mechanism that led the Soviet
Union to drop its objections to SDI.[5]

The documents that have become available recently allow to
reconstruct the Soviet response to the Star Wars program in more detail.[6]
The goal of this paper is to introduce these documents and to discuss the
implications that the new information has on the discussion of the role of the
SDI program. As can be expected, the documents present a complex picture of the
Soviet response. Just as in the United States, there has never been a uniform
and consistent view of the Star Wars program in the Soviet Union. The
negotiation positions and policies of the Soviet state were a result of a
complex process of interaction between various institutions involved in the
decision-making - from the military to the defense industry and to the
political leadership. On the balance, however, the documents support the view
that the SDI program, while affecting Soviet policies, did not help bring the
cold war closer to the end. Instead of facilitating the arms control process, SDI
seriously complicated it, creating an unnecessary obstacle that the Soviet
leadership, eager to move to arms reductions, had to deal with. Finally, the
evidence suggests that one of the basic premises behind the SDI program - that
it would be able to shift the arms race to the areas of advanced technologies,
dissuade the Soviet Union from competition, and eventually provide a more
stable defense-dominated environment - did not work. While the SDI program had
failed to produce any result, the Soviet Union had developed and was ready to
deploy a range of weapon systems that would have brought the U.S.-Soviet
confrontation to a more dangerous new level.

First reaction to SDI and return to negotiations

The first reaction of the Soviet Union to the President
Reagan's address of March 23, 1983, in which he announced the program that
would later become known as the Strategic Defense Initiative, was resolutely
negative. The Soviet leadership immediately accused the United States of
attempting to undermine the existing strategic balance. The missile defense
plan, the Soviet Union argued, aimed at giving the United States a first-strike
capability and denying the Soviet strategic forces their retaliatory potential.[7]

This assessment of the potential role of the defense was
in line with the understanding of the link between offense and defense that was
predominant in the Soviet Union as well as in the United States at the time.
For example, in a National Intelligence Estimate issued in 1983, the U.S.
intelligence community, estimating potential role of the Soviet missile defense
system, argued that

"the Soviets probably would not
have high confidence in how well [their missile defense] systems would perform
against a large-scale, undegraded U.S. missile attack [...]. However, the Soviets
would probably view their ballistic missile defenses as having considerable
value in reducing the impact of a degraded U.S. retaliatory attack [...]"[8]

Applying exactly the same logic to the U.S. missile
defense plan, the Soviet Union could only conclude that the goal of the defense
system proposed by Reagan was to weaken the deterrence potential of the Soviet
forces. In addition to this, the Soviet Union apparently considered the U.S.
strategic force modernization program, initiated in the late 1970s-early 1980s,
as leading to a substantial increase in the counterforce potential of the U.S.
forces. Even more ominous was the upcoming deployment of U.S. missiles in Europe,
which would theoretically give the United States the capability to attack
targets on the Soviet territory on a very short notice.[9]
From the Soviet point of view, all these steps, taken together, clearly
amounted to a coordinated effort on the part of the United States to
unilaterally change the existing strategic balance. The fact that the new
defense system was supposed to rely heavily on space-based components certainly
convinced the Soviet leadership that the concerns about the military potential
of the U.S. space program were fully justified.

In terms of practical steps, the most visible part of the
Soviet response was the diplomatic and propaganda measures that it undertook at
the time. The Soviet Union tried to seize the opportunity presented by the
discussion of space-based systems to draw attention to the attempts to limit
weapons in space and anti-satellite weapons in particular. In a major
initiative in this area, in August 1983 the Soviet Union introduced a new draft
treaty that would ban space-weapons and announced a unilateral moratorium on
further tests of its ASAT systems.[10]
Although the proposed ban on weapons in space would have certainly affected
SDI-related programs, the Soviet initiative did not appear to be a direct
response to the U.S. program. Rather, it was an extension of its earlier
efforts to reach a ban on space weapons as well as a reaction to the efforts of
the international scientific community to prohibit development of
anti-satellite systems.[11]
These efforts, however, proved unsuccessful, mainly because of the sharp
deterioration of the U.S.-Soviet relations in the fall of 1983 and the Soviet
walkout from arms control negotiations that followed beginning of deployment of
U.S. intermediate-range missiles in Europe in November 1983.

The Soviet documents of the time strongly support the
conclusion that the Soviet initiatives of 1983 were not a direct response to
the Star Wars program. Neither the Soviet political leadership nor the military
or the defense industry showed any appreciation of the scale of the program or
its technologies, let alone take it into account in their deliberations about
diplomatic initiatives or development of the Soviet strategic forces.[12]
This is hardly surprising, though, for the Strategic Defense Initiative had not
been formally established until 1984, when the scale of the program became
clearer.[13]

Following the crisis of the 1983 the Soviet Union and the
United States spent most of 1984 trying to break the deadlock that followed the
deployment of U.S. missiles in Europe and the Soviet walkout from the arms
control negotiations. In November 1984 these efforts resulted in an agreement
to resume the talks, in a new format that included parallel talks on space
weapons, strategic offensive forces, and intermediate-range nuclear forces.

This period of time is very important for understanding
the role that the U.S. Strategic Defense Initiative may have played in the
U.S.-Soviet arms control negotiations. SDI has sometimes been credited for the
success in resuming the negotiations, primarily on the basis of the fact that
the Soviet Union insisted that the negotiations cover space weapons.[14]
The facts, however, do not support this interpretation, suggesting instead that
SDI played a much more limited role and most likely made the return to the
talks more difficult.

While it is true that the Soviet Union insisted on
negotiating a ban on weapons in space before beginning any discussion of
offensive force reductions, this position was a result of the belief that the
reductions are impossible without limits on missile defenses, rather than of
any specific concerns about the SDI program. Eventually, it was the U.S.
administration that had to accept this position and agree to include space
weapons into negotiations.[15]
This opened the way for the Soviet Union to reconsider its position on linkage,
although it still insisted that reductions would not be possible without
limiting the defense first. It was even suggested that if an agreement on
offensive forces reductions were achieved before the one on space weapons its
implementation should be postponed until the space part of the negotiations is
concluded.[16]

In the end, there is no evidence that would suggest that
the ban on space-based weapons or limits on SDI was the primary goal that the
Soviet Union set for the negotiations. On the contrary, the Soviet side
considered the issue of space weapons and SDI as an obstacle that had to be
removed before the discussion of reduction of offensive forces could begin. Had
this not been the case and the limit on SDI were of a higher priority for the
Soviet Union, one would expect it to adjust its position on strategic forces
and intermediate-range missiles in Europe. This, however, did not happen and
the Soviet had not made any significant adjustments of its negotiating
positions compared to the ones it had in 1983.[17]

Another, much less visible part of the Soviet response to
the Strategic Defense Initiative proposal was a series of decisions that
accelerated development of its own defense programs. Unlike the political and
military leadership, the defense industry was quite enthusiastic about the U.S.
initiative, seizing the opportunity to advance its projects.[18]
The initial steps in this area, however, strongly indicate that the industry
did not consider the U.S. program as something radically new or separate from
the efforts in space-related research and development that the United States
had already carried out. The programs that were considered by the Soviet Union at
the time were either continuation of old development efforts or a direct
response to the U.S. programs that were outside of SDI. Two examples of this
pattern are the overview of the "Skif" space-based laser program and the
decisions to begin development of the "Kontakt" air-based anti-satellite
system.

The "Skif" program falls into the category of old
development efforts that received an apparent boost from the U.S. Strategic
Defense Initiative. The goal of the "Skif" program, initiated in 1976, was to
build a space-based anti-satellite laser that would take advantage of the
capabilities provided by the Buran launcher, the Soviet version of the U.S.
Space Shuttle.[19] By
1984, however, the program had still to produce any hardware, being held back
by the lack of a dedicated laser that would be suitable for deployment in
space. In the summer of 1984, the Ministry of General Machine Building, which
was overseeing the program, ordered development of a demonstration spacecraft,
"Skif-D", which was supposed to carry on board the gas-dynamic laser developed
for the "Dreif" airborne laser program.[20]
In the end of 1984 the new direction of the "Skif" program was approved by the
government. The research on lasers was expected to continue with the type of
laser to be eventually deployed on "Skif" to be determined in 1986.[21]
There is no direct evidence that would link the decision to accelerate the
"Skif" program to the Strategic Defense Initiative. The most likely reason the
"Skif" program got an overhaul in 1984 was the approaching start of operations
of the Energia launcher. At the same time, it is reasonable to assume that the
U.S. SDI proposal created the atmosphere that made it easier for the Soviet
industry to lobby for development of its own similar systems.

Unlike with the case of "Skif", there is virtually no
uncertainty about roots of the decision to launch the "Kontakt" program -
development of an air-based ASAT system. This program was clearly a direct
response to the similar U.S. system that was under active development at the
time and had been tested twice in 1984.[22]
As it happened, the decision to begin the Soviet program was made two
weeks after the second U.S. test. Like
its U.S. counterpart, the Soviet system was to use a rocket launched from an
aircraft to target satellites on low-earth orbits. Flight tests of the new ASAT
system were expected to begin in 1989.[23]
These plans did not materialized and there is no evidence that the system has
ever reached the stage of flight tests. However, it had been in active
development until at least 1989-1990 and was not suspended when the U.S.
Congress imposed a moratorium on further U.S. ASAT tests in 1985.

The example of the "Kontakt" program shows that although
SDI appeared to be dominating the agenda, it was not a major factor in the
decisions that were being made by the Soviet Union at that time. The industry
did not try to frame the "Kontakt" program as an anti-SDI effort, relying
instead on a proven argument that it has to develop systems similar to those of
the United States. Even later, when a number of anti-satellite programs were
indeed promoted as "anti-SDI", the "Kontakt" system was still considered in a
separate category.[24]

Although the industry's initial response to the SDI
program was rather constrained, it does not mean that the U.S. initiative was
not taken seriously. By the early 1980s the Soviet industry had had some
experience with the directed-energy weapon technologies that were supposed to
became the key element of the future U.S. defense system. That experience was
apparently mixed, raising a legitimate question as to what extent the United
States would be more successful in making working weapons based on these
technologies.[25] Shortly
after the U.S. announcement, the industry initiated an effort to evaluate the
status of directed energy weapons technologies. The Military Industrial
Commission set up a commission that included scientists as well as
representatives of the military and the defense industry. The main conclusion
of the commission, chaired by Evgeny Velikhov, was that deployment of
prototypes of weapon systems based on directed energy technologies would be
unlikely before about 2000.[26]

The Velikhov commission set up by the Military Industrial
Commission was not the only effort to evaluate the U.S. SDI program. The most well
known of these is a study group organized by Evgeny Velikhov and his colleagues
at the Committee of Soviet Scientists. That group, working in close cooperation
with scientists from the United States, issued a number of public reports on
SDI technology and its potential effect on strategic stability, which were well
known in the United States and in the Soviet Union.[27]
It is almost certain that the conclusions of the report commissioned by the
defense industry were very close to those of the public reports.

The military also launched their own studies to evaluate
the Strategic Defense Initiative. These were done at various levels - from the
defense minister to departments at the research institutes of armed forces
services.[28]

Despite their overall skeptical assessment of the
prospects of SDI technologies, neither of these reports was able to prevent the
Soviet industry from pushing for a broad development effort that would emulate
the U.S. SDI program. In fact, internal reports called for continuing research
in the area of directed energy technologies, which may have helped the industry
to make its case.[29]
The concerns of the political and military leadership about potential
destabilizing effects of new missile defenses played essentially no role,
mostly because the decision-making process in the industry normally did not
take these considerations into account. As a result, by the summer of 1985, the
Soviet defense industry had prepared its own program that was supposed to
become the Soviet response to SDI. This program is described in the next
section.

Symmetric response

The series of decisions made in the summer of 1985 was
arguably the high point of the Soviet response to the U.S. Strategic Defense
Initiative program. By that time the defense industry had consolidated its
proposals and presented the Soviet leadership with a large-scale program that
was intended to significantly expand the work on missile defense, military
systems in space, and a range of other programs as well.

A decision of the Central Committee and the Council of
Ministers of 15 July 1985 approved a number of "long-term research and
development programs aimed at exploring the ways to create a multi-layered
defense system with ground-based and space-based elements." It should be noted
that no commitment to deployment of any of these systems was made at the time.
The goal of the research and development effort was "to create by 1995 a technical
and technological base in case the deployment of a multi-layered missile
defense system would be necessary."[30]

The July 1985 decision approved two major "umbrella"
programs, each of which encompassed an array of projects that ranged from
fundamental exploratory research to development of specific systems ready for
flight tests. The first of these two, known as "D-20" included research and
development in the area of ground-based missile defenses. The responsibility
for this program was assigned to the Ministry of Radio Industry, which
traditionally worked on missile defense, early warning, and command and control.
The second program, "SK-1000", was a product of design bureaus of the Ministry
of General Machine Building, which was responsible for the missile and
space-related research, development and production. This program concentrated
on space-based missile defenses and on anti-satellite systems, both
ground-based and space-based. Most of the projects included that were
concentrated in these two large "umbrella" programs existed before 1985, but
some were either significantly upgraded or entirely new efforts.[31]

At the core of the "D-20" program were the projects
associated with the Moscow missile defense. The mainstay of the program, the
A-135 system, was to be prepared for tests in 1987. In addition to that, the
schedule approved in 1985 directed the industry to complete a draft design of
the A-235 and a preliminary design of the A-1035 follow-on systems by 1988.[32]
These two systems had been in development for some time - the government first
approved them in 1978. They were expected to provide defense of the "Moscow
industrial region" and "main administrative centers and military objects"
respectively.[33] The
systems were expected to include a number of advanced components, beyond what
was designed for its predecessor.[34]
At least two of these components - an airborne sensor and an advanced
discrimination radar - were included into the "D-20" program.

In addition to the line of missile defense systems that
were oriented toward protection of Moscow and other population centers, the
"D-20" program included another line of defenses - "close-range" systems,
designed to protect military objects and missile silos in particular.

The first of these projects, the S-550 system, was
essentially a continuation of an earlier effort to develop a short-range
endoatmospheric intercept system, known as S-225, which goes all the way back
to the early 1960s. The S-225 system had been usually considered a contender
for the endoatmospheric intercept in the A-135 and similar systems discussed in
the 1960s and 1970s.[35]
The project was terminated in the early 1980s and what was left of it was
folded into the A-135 program.[36]
From the history of the S-225 it appears that the S-550 program may have begun
before 1985.[37] In any
event, the July 1985 decision, which included it into the "D-20" program, gave
this project an additional boost.[38]
S-550 was expected to be a mobile or at least relocatable missile defense
system that would protect "objects of special importance". It was scheduled to
begin flight tests in 1990 and be ready for deployment in 1992.[39]

Another system, "Sambo", was developed specifically for
defense of ICBM silos. Details about this system are scarce, but it appears to
be a version of the Swarmjet idea that was discussed in the United States at
the time.[40]
According to this concept, incoming warheads would be intercepted at a very
close range above a silo, which made intercept easier, but required a hardened
silo that would still have to withstand a nuclear blast. The "Sambo" system appeared
to rely on rods to destroy incoming warheads.[41]
The "Sambo" program was expected to produce a prototype in 1987 and reach the
stage of tests in 1989.[42] A
year or so later, "Sambo" was either absorbed or replaced by another program of
this type, known as "Mozyr". This system was described as an "active two-tier"
defense and it was supposed to use short-range interceptors with conventional
explosive warheads. It was expected to reach the deployment stage by 1991.[43]

In addition to the projects described above, the "D-20"
program included a number of research and development projects in areas of
system integration, large computers, warhead and decoy discrimination sensors
and systems, new interceptors and their warheads, and study of ground-based
directed-energy weapons. Most of the programs were research projects that were
expected to produce initial reports in the 1988-1989 time frame.

The second program approved by the July 1985 decision,
"SK-1000", was more in line with the Strategic Defense Initiative vision. It
included a variety of projects that explored a possibility of developing
space-based missile defenses, anti-satellite systems, and of what the Soviet
Union traditionally called "space-strike weapons" - systems designed to attack
targets on earth from space. Like its more conventional counterpart, "SK-1000"
was a combination of projects that began in the 1970s and of some new ones. The
majority of "SK-1000" programs were devoted to fundamental and applied
research, but there were some prominent development projects as well.

The most advanced part of "SK-1000" was the series of
anti-satellite programs that were intended to attack "combat and information
support satellites, in particular those that are part of the space-based tier
of the U.S. missile defense system."[44]
The development programs approved by the July 1985 decision included the "Skif"
and "Kaskad" space-based systems, which had been in development since the
1970s, and two new anti-satellite programs - "Kamin" to develop space mines and
"Naryad-V" to create a ground-based ASAT system. There were also two research
projects that explored weapons based on "other physical principles".[45]

The concept of "Naryad-V" was similar to that of the "IS"
anti-satellite system that the Soviet Union deployed in the early 1970s. The
new project, however, was completely under control of the Ministry of General
Machine Building, unlike "IS", where a design bureau of the Ministry of Radio
Industry was the primary developer.[46]
The "Naryad-V" system was expected to use missiles of the UR-100NUTTH/SS-19
type or their modifications to launch its interceptors to satellites on orbits
ranging from low-earth to geosynchronous. In 1985 it was projected that the
system would be ready for flight tests in 1987. The "Kamin" development program
had a much more distant goal - it was not expected to produce a draft project
until 1989. Flight tests of the system were not expected to begin until 1992.[47]

Other weapon-related components of the "SK-1000" program
were a series of research projects to investigate a possibility of using directed
energy weapons for boost-phase and exoatmospheric intercept of ballistic
missiles and their warheads, studies of "space-strike weapons", and a number of
development projects to improve hardness of military satellites and protect
them from an attack. Most of these were research projects that were expected to
produce preliminary reports in 1987-1989.

"SK-1000" also in included virtually all space launcher
and satellite programs that were underway in the Soviet Union at that time -
from the Energiya-Buran heavy launcher and the Mir orbital station to optical
and electronic reconnaissance, communication and navigation satellites. A
number of development programs were dedicated to improving the command and
control system of the space forces. Although most of these projects clearly had
existed before the July 1985 decision, bundling them together with the anti-SDI
program was probably the way for the industry to get more reliable access to
resources.

Arms control takes over

The decisions made by the Soviet government in July 1985
indicated a major commitment to development of a broad range of missile defense
and space weapons technologies. The defense industry was clearly taking
advantage of the situation created by the U.S. initiative to increase the
levels of funding and get access to additional resources for its programs.
Another factor that contributed to the decision to approve this kind of
confrontational response was the actively discussed in the United States
possibility of ending its compliance with the SALT II Treaty.[48]
Although the United States eventually decided to stay within the treaty limits,
that discussion clearly added to the impression, already dominant in the Soviet
Union, that the existing structure of arms control treaties was falling apart.[49]
In this situation, those in the political and military leadership who had
serious reservations about potential destabilizing effects of missile defenses
could not present a viable alternative to the course of actions proposed by the
industry. That alternative to the industry push would eventually emerge with
the changes in the U.S.-Soviet relationships, through a complex process of
trial and error that involved decisions regarding specific weapon programs,
development of negotiating positions and initiatives, and evaluation of
technical perspectives of missile defenses.

Evolution of one of the programs, the "Skif" space-based
anti-satellite laser system, can serve as a good illustration of this process.[50]
As described in previous sections, in 1984 a delay with the laser caused the
program to be reoriented toward producing a demonstrator spacecraft, "Skif-D".
That spacecraft would still have a laser on board, although not of the kind
that could be used in anti-satellite missions. It was expected to be ready for
its first flight by the end of 1987. The decisions of July 1985, however,
called for an accelerated deployment schedule. The industry was ordered to
produce a spacecraft that would be flown as early as 1986, even though that
meant that it would be only a mockup and would not have much of functioning
equipment on board. The new spacecraft was designated "Skif-DM".

The acceleration of the "Skif" program was matched by a
decision to move forward the first launch of the "Energiya" heavy launcher,
which was expected to deliver "Skif-DM" into orbit.[51]
The defense industry considered the "Energiya" and "Skif-DM" among its
highest-priority projects, for they could demonstrate that the industry is
capable of building complex space-based systems, justifying and legitimizing
the "symmetric" programs developed in response to SDI.

The "Skif-DM" program proceeded at accelerated pace and by
the fall of 1986 the work on the spacecraft was largely completed. The test
flight of the "Energiya" launcher with "Skif-DM" spacecraft was scheduled to
take place in the spring of 1987. The spacecraft, which was initially conceived
as a mockup, now incorporated some elements that made it somewhat more than a
simple weight imitation payload. Among these were a cueing and targeting system
that included a radar and a low-power laser and a set of sophisticated targets
to be separated from the spacecraft during a test of the cueing and targeting
mechanism. The spacecraft was also supposed to test a recoilless exhaust system
for a gas-dynamic laser that was to be installed in subsequent flights.

If the decision to build a spacecraft that would perform a
variety of weapon-related experiments in orbit seemed natural in 1985, it
appeared much less so in the end of 1986. The summit meeting in Reykjavik in
October 1986, where the issue of testing of missile defense systems in space
played a very prominent role, apparently forced the Soviet leadership to pay
closer attention to the effect that its programs in space may have on the
Soviet position at the negotiations.[52]
This change was probably responsible for the decision taken by the state
commission, which gave the final approval to the "Skif-DM" flight, to exclude
everything that could resemble tests of space-based weapon systems. In February
1987, the experiments that included separating of targets and tracking them
with a radar and laser were cancelled. Also cancelled was the experiment that
would emulate work of a gas-dynamic laser in space.[53]

By the time the "Energiya" system was ready for launch in
May 1987, the mission was very close to being cancelled. The Politburo gave its
approval to the launch at the very last moment.[54]
The launch itself, which took place on May 15, 1987, was only partially
successful - the "Energiya" launcher performed well, while the "Skif-DM"
spacecraft failed to reach orbit because of a software error in its guidance
system. This probably helped the Soviet Union to avoid a major diplomatic
setback. Even though most of the experiments on board of the spacecraft had
been cancelled, it is likely that a success of the "Skif-DM" mission would have
complicated the efforts to limit development of space-based weapon systems.

The apparent controversy that surrounded the test flight
of "Skif-DM" in May 1987 reflected the fundamental shift in priorities that
happened since the program was approved in 1985. If in 1985 the program was
seen as one of the central elements of a strategy that would preserve strategic
balance, in 1987 the Soviet political leadership considered this program an
impediment to its efforts to reach an arms control agreement with the United
States. Without the political support the program quickly ground to a halt.
Although no formal decision to terminate the "Skif-D" project was made, by
September 1987 all work on the new spacecraft had stopped.[55]

Other components of the "SK-1000" program that involved
research and development of directed energy weapons also suffered a setback.
There is no evidence that would indicate that work on these projects continued
after 1987.

Development of traditional missile defenses, which was at
the center of the "D-20" program, also reached a major turning point in 1987.
The flagship project in this area, the A-135 Moscow missile defense system, was
a much less controversial undertaking than the directed energy projects of the
"SK-1000" program. The system was compliant with the ABM Treaty and was
compatible with the Soviet negotiating positions. Deployment of the A-135
system had all the signs of a high-priority project. In February 1987 Mikhail
Gorbachev visited the construction site of the Don-2N battle management radar
in Pushkino.[56] Later
that month the management of the program was consolidated and strengthened to
ensure that construction of the radar will be completed by November 1987. In
March 1987 the developers of the A-135 system conducted first flight tests of
interceptors at the prototype system at Sary-Shagan.[57]

The construction of the Don-2N battle-management radar of
the Moscow missile defense was indeed completed in October 1987, but the
military insisted that the system needs additional work and is not ready for
service. Work on the system continued with tests of radars and interceptors
conducted in 1988-1989. The system was finally accepted "for experimental
service" in December 1989.[58]

Despite the delays, the A-135 program was generally
successful by the Soviet standards. It was fairly common for new weapon systems
to begin service in "experimental mode", while the designers worked on
addressing the problems discovered during tests. However, starting in 1987 the
work on the A-135 system and its successors, A-235 and A-1035, slowed down
quite significantly. This development reflected the changes in the assessment
of the role that these systems could play. In contrast with the optimistic
assessments of missile defense performance that were characteristic for the
days when the "D-20" program was approved, estimates of 1987 showed that the
role that systems like A-135 or its successors could play is much more limited.
As part of the studies conducted within the "D-20" program, the military had
developed technical specifications for missile defenses, which required the
kind of performance that was technically unrealistic.[59]
In another important development, the upcoming agreement on elimination of
intermediate-range missiles in Europe removed a key part of the mission of
these missile defense systems.[60]
As a result, while the work on the A-135 system continued, it apparently was no
longer a high-priority project. Deployment of interceptors around Moscow began
only in 1990 and was not completed until 1992.[61]

Asymmetric response

The decline of interest in active missile defenses was
accompanied by growing confidence in the capabilities of countermeasures that
were supposed to defeat U.S. missile defense systems. Although some programs in
these areas can be traced back to at least 1984, the coordinated effort in this
area began after the Reykjavik summit. On October 14, 1986, two days after the
end of the Reykjavik meeting, the Politburo asked the Ministry of Defense to
present its proposals on the structure of the strategic offensive forces should
the United States and the Soviet Union reach an agreement on arms reductions.
Politburo also asked the military and the industry to prepare proposals that
would "accelerate the work on countermeasures against a possible deployment by
the United States of a multilayered national defense system and against its
space-based component in particular."[62]
The result of this effort - the "Protivodeystviye" and "Kontseptsiya-R"
programs - was presented to the Defense Council in July 1987.[63]
Shortly after that the programs were approved by a decision of the Central
Committee and the Council of Ministers.[64]

As it was the case with the "symmetric response" programs,
"D-20" and "SK-1000", the countermeasure efforts were managed by two different
ministries. "Protivodeystviye" was managed by the Ministry of General Machine
Building, and "Kontseptsiya-R" - by the Ministry of Radio Industry.[65]
Although these programs did not seem to take final shape until the end of 1986,
some of their core projects began in 1984 or earlier.[66]

"Protivodeystviye" appears to be a follow-on to an earlier
research and development program, known as "SP-2000", which was a broad effort
aimed at modernization of the strategic offensive forces. It included
subprograms that were dealing with each component of the strategic triad as
well as research in the area of strategic command and control.

Most of the efforts in "SP-2000" predictably went into the
projects that explored the ways to increase survivability of land-based
ballistic missiles and development of countermeasures specifically designed to
counter space-based missile defenses. The "SP-2000" program included
modernization of the strategic missiles that were expected to remain in service
through the 1980s and 1990s - R-36M2/SS-18, RT-23UTTH/SS-24, Topol/SS-25, and
Kurier/SS-X-26. The intermediate-range Pioner/SS-20 missile was also expected
to undergo modernization to improve its ability to penetrate missile defenses.
All projects of this kind involved two stages - a short-term improvements in
survivability and a longer-term research that aimed at exploring additional
measures that would increase the effectiveness of missile defense penetration.
But none of these were crush programs - they were expected to produce draft
technical projects by 1988-1989 and none of the programs had a set date for
flight tests.

Specific measures that were supposed to improve
effectiveness were subject of separate research programs that were also part of
the "SP-2000" program. Most of these were widely discussed in the context of
SDI countermeasures at the time - shorter boost phase, rotation of missile
bodies, reduced detection signature of warheads, penetration aids, methods of
blinding missile defense sensors, etc. All these were relatively long-term
research projects that were expected to produce preliminary results by the end
of the 1980s.

At first, the "SP-2000" program apparently concentrated on
incremental modernization of the existing ICBMs, avoiding any major new
development projects. But the program eventually was taken advantage of to launch
new projects as well. The NPO Mashinostroyeniya design bureau developed a
concept of an intercontinental missile with a gliding reentry vehicle,
presenting it as one more way to defeat the U.S. missile defense. This project,
known as "Albatros", was added to the "SP-2000" program in 1987.[67]

Regarding the strategic fleet, the "SP-2000" program
mostly focused on modernization of the R-29 (SS-N-20) and R-29RM (SS-N-23)
sea-launched ballistic missiles. It also included research on two new SLBMs - a
small single-warhead "West" and a MIRVed "Ost". Both these projects existed
before 1985, but they were apparently at the early stages - neither missile was
expected to reach the stage of flight test until at least mid-1990.[68]

The part of the "SP-2000" program that addressed strategic
aviation included research on improving hardness of cruise missiles and
reducing their signature as well as a research on a new low-altitude long-range
cruise missiles. The program also included an unusual project, "Podzol", that called
for deployment of intermediate- and long-range cruise missiles carried by Mi-26
helicopters.

If the "SP-2000" program included projects that could be
classified as "passive" countermeasures, the other "asymmetric response"
program, "Kontseptsiya-R" was an effort that was designed to counter the SDI
system by directly attacking its satellites. The main purpose of the "Kontseptsiya-R"
program was to consolidate the anti-satellite efforts that were under control
of the Ministry of Radio Industry, namely the "Kontakt" air-based system and
the "IS-MU" upgrade of the "IS-M" ground-based ASAT. Both these systems had
been under development since at least 1984. "IS-MU" was expected to begin
flight tests in 1987-1988, "Kontakt" - in 1989. Another project that
Minradioprom included under the "Kontseptsiya-R" umbrella appeared to be a new
effort - development of a non-nuclear interceptor for the A-135 Moscow missile
defense system that would give the system the capability to attack satellites
on low earth orbits. A draft technical project of the ASAT interceptor for the
A-135 system, "Amulet", was to be completed in 1989, which means that no flight
tests of that system would be expected until about mid-1990s.

In addition to the anti-satellite projects,
"Kontseptsiya-R" included all other space-related programs that were conducted
by Minradioprom - development of the US-KMO early-warning satellite system that
would provide coverage of oceans as well as of the U.S. territory,
modernization of the space-surveillance network and its integration with the
anti-satellite systems.

Although the concept of countermeasures or anti-satellite
systems that could target SDI satellites had been known and discussed long
before 1987, the approval of the "Protivodeystviye" and "Kontseptsiya-R"
programs was a very important step. These programs offered a very detailed and
specific set of measures that were within the reach of the Soviet defense
industry - most projects used proven technology, did not require any
technological breakthroughs, and were relatively inexpensive.[69]
At the same time, technical assessment of the effectiveness of these measures
was based on the detailed knowledge of projected capabilities of SDI systems
that had been accumulated by that time.

All this gave the Soviet military and political leadership
the necessary confidence to pursue arms reductions with the United States.
Although technically the issue of missile defense and the ABM Treaty were still
discussed at the negotiations, at the summit meeting in Washington in September
1987 the Soviet Union effectively dropped the issue.[70]

Specific measures that were included in the "Protivodeystviye"
program concentrated on improving the capabilities of ballistic missiles to
defeat or penetrate space-based defenses. Among those designed for the boost
phase were development of new engines that would allow shortening it,
protecting missile bodies with heat absorbing material and implementing
rotation of missiles. The countermeasures that were supposed to work during
midcourse flight included new penetration aids, maneuverable warheads, and
gliding reentry vehicles.[71]

As part of the effort to defeat missile defenses during
boost phase, the Soviet Union conducted a detailed study of a "modular missile"
concept. This concept called for a modification of R-36M2/SS-18 and
RT-23UTTH/SS-24 missiles that would equip them with multiple second stages -
eight in the case of R-36M2 and from five to ten in the case of RT-23UTTH. As a
result, the missile would create multiple targets much earlier in the powered
flight, complicating the job of boost-phase missile defense. According to the
estimates that were done for the project, the modification could have been made
without significant loss of throw weight and would substantially increase the
probability of penetrating the defense.[72]

A separate set of measures in the "Protivodeystviye"
program addresses issues of vulnerability of silo-based missiles. The Soviet
Union considered concepts that were very similar to the Multiple Protective
Shelter (MPS) and "Densepack" basing modes suggested for the MX missile in the
United States. The shelters were supposed to host RT-23UTTH/SS-24 missiles,
"Densepack" silos - small single-warhead missiles.[73]
In addition to that, silos of R-36M2 missiles were to be hardened to the level
of 300 atm (4500 psi). In all these basing modes silos were to be protected by
a close-range missile defense system, "Mozyr", which was developed as part of
the "D-20" program.[74]

None of the "Protivodeystviye" countermeasures or
deployment schemes have been implemented, mostly because they were created as
contingency plans, designed to be employed only in the case the United States
and the Soviet Union failed to reach an agreement on reductions of strategic
offensive forces or in the case the United States withdrew from the ABM Treaty.[75]
Another reason was that the Soviet offensive forces were caught in the middle
of a modernization cycle, which began around 1983. Implementation of any new
measures had to be incorporated into the next generation of strategic systems,
which was not expected to be deployed until about mid 1990s. The
"Protivodeystviye" program in effect reconciled the response to SDI with the
modernization schedule, providing assurance that the countermeasures could be
implemented in time and be effective.[76]
In any event, the existence of these countermeasure plans was an extremely
important element of the process that allowed the Soviet leadership to proceed
with reductions of strategic offensive weapons.

Programs that were implemented

The ability of the defense industry and the military to
come up with an assessment of the U.S. missile defense program and develop a
set of specific programs to counter its possible deployment played a very
important role in advancing the U.S.-Soviet arms control negotiations. The
converse is true as well - the arms reduction dialogue was consistently
undermining the case for the Soviet defense programs, diverting political
support to disarmament, conversion of defense industry, and more efficient
military spending.[77]
This change of priorities resulted in suspension of a number of programs that
were approved earlier.[78]

In this situation a number of projects that were included
in the anti-SDI programs continued into 1989-1990 and beyond. As could be
expected, the competition for resources and political support selected those
projects that were considered most practical, effective, and inexpensive,
eliminating most of the big-ticket exotic technologies like directed energy
weapons.

Three projects emerged from the competition and managed to
reach the stage of flight tests by 1990. These were the "Albatros" missile
system, "Naryad-V" and "IS-MU" ground-based anti-satellite systems. A few
others were still considered active at that point, even though there were
doubts about their viability: the "Kontakt" air-based ASAT, two space-based
systems - anti-satellite interceptors "Kaskad" and space mines "Kamin", as well
as the "Amulet" project, that called for development of an anti-satellite
interceptor for the Moscow missile system.[79]

Since its inception in February 1987, the "Albatros"
missile project had undergone a very serious transformation. Initially, the
program was expected to produce a new solid-propellant intercontinental
ballistic missile that would be deployed in silos, on road-mobile launchers,
and in "relocatable silo" mode, apparently similar to the Multiple Protective Shelters.
The missile was supposed to carry a gliding reentry vehicle, which would use
the atmosphere during most of its flight to avoid detection and to defeat
missile defenses. However, the draft technical project of the missile failed to
get an approval and this part of the program was cancelled in September 1989.[80]
Development of the gliding reentry vehicle continued and it was tested in
flight at least twice in 1990.[81]
The flight test program was expected to continue, but it was eventually
interrupted by the breakup of the Soviet Union in 1991. The project, however,
was preserved and the reentry vehicle was tested again in February 2004, this
time presented as part of Russia's response to the current U.S. missile defense
deployment plans.

The missile part of the "Albatros" program continued as
another project. In 1989 development of a new single-warhead solid-propellant
missile, designated "Universal" was assigned to two design bureaus. The Yuzhoye
design bureau got the order for a silo-based missile, and the Moscow Institute
of Thermal Technology (MITT) - the road-mobile version. By 1991 the Yuzhnoye
design bureau produced a prototype ready for flight tests, but because of the
breakup of the Soviet Union that missile was never launched.[82]
After the breakup, the project was transferred to MITT, where the development
of the missile, now known as Topol-M/SS-27, was successfully completed. In 1997
the first two missiles of this type were deployed in silos and in 2006 the
first regiment of road-mobile missiles was accepted for service.

Deployment of the "IS-MU" anti-satellite system was quite
a controversial project. Although the earlier version of the system, "IS-M",
was nominally still on combat duty, the technology that it used was outdated
and the system required substantial modernization. In addition to that, the
Soviet Union was still bound by its unilateral moratorium on ASAT test
announced in 1983, which complicated the work on the modernization. During
1989-1990, there were several attempts to terminate the project, initiated by
the Foreign Ministry, which sought to use this measure to strengthen the Soviet
negotiating position. The industry, however, successfully fought off these
attempts, arguing that the Soviet Union would need "IS-MU" to destroy satellites
of the U.S. missile defense system or at the very least could use it as a
leverage at the negotiations.[83]In the end, the "IS-MU" system had been
deployed and was accepted for service in April 1991.[84]
It was decommissioned in August 1993.

The other ground-based anti-satellite system, "Naryad-V",
was very similar to "IS-MU" in basic architecture. It was designed to be a more
capable system that would target satellites at all altitudes - from low-earth
to geostationary orbits. Instead of relying on a dedicated launcher, like the
"IS" systems did, "Naryad-V" interceptors were built to be deployed on regular
silo-based UR-100NUTTH/SS-19 missiles.[85]
That would allow for a massive deployment of interceptors - as many as one
hundred were discussed at one point.[86] The
designers were pushing for a flight test of the interceptor, which took place
in a suborbital flight on 20 November 1990.[87]
No further tests of the system appear to have been performed after that, but
the program has been preserved and probably could be reinstated.[88]

As for the rest of the programs that were still active in
1990 - air-based ASAT, space-based interceptors, mines, and anti-satellite
interceptor for the Moscow missile defense system, there is no information on
their progress after the breakup of the Soviet Union. It is most likely that
they were terminated shortly after that.

Conclusions

As could be expected, the data on the Soviet strategic
programs in the 1980s clearly show that the U.S. policies and actions and its
strategic buildup and the Strategic Defense Initiative program in particular,
had a significant impact on the choices made by the Soviet leadership at that
time. However, the nature of this influence, its mechanisms and the effect of
the U.S. actions strongly indicates that these actions did not help bring the
end of the Cold War.

The new evidence on the Soviet response to SDI largely
corroborates the prevailing view that the Soviet Union eventually realized that
this program does not present a danger to its security, for it could be
relatively easily countered with simple and effective countermeasures. The
evidence also helps answer some important questions about the concerns that the
Soviet Union had about the U.S. program, the reasoning behind the choices that
the Soviet leadership made, and the process that led to those choices.

The Strategic Defense Initiative clearly emerges as an
impediment to the disarmament process rather than a factor that helped compel
the Soviet Union to engage in the arms reduction talks or agree on deeper
reductions of its offensive forces. The documents show that internal estimates
made by the Soviet military and by the defense industry did not specifically
consider SDI and its potential effect until about 1985, which was after the
Soviet Union and the United States resumed the negotiations broken off in
November 1983. Neither did the Soviet Union seriously change its positions on
key issues during that time. All this strongly suggests that SDI did not play a
role in the decision to return to the disarmament talks.

When the negotiations began, the U.S. effort to build a
missile defense system did become one of the points of disagreement. In
particular, it was one of the central issues at the summit meetings in Geneva
in November 1985 and in Reykjavik in October 1986, with the Soviet Union
strongly insisting on curbing the program and the United States resisting the
effort. That persistence, however, was not caused by any specific concerns
about projected capabilities of SDI systems. Rather, it was an effort to deal
with the issue of missile defense in a way that would allow moving on to the
disarmament agenda in which the Soviet Union was clearly interested. This
interest manifested itself in the extreme reluctance of the Soviet leadership
to embrace a kind of response to SDI that would include freezing or building up
its offensive forces. There are no signs in the documents of the time that
would suggest that the Soviet Union in its international deliberations and
assessments of the situation ever considered 'trading in' its strategic forces
in exchange for limits on SDI. Quite the opposite, the Soviet Union was fully
prepared to wait this situation out, postponing reductions of offensive forces
until the United States reconsidered it position on missile defense. The effort
to restrict defenses was also motivated by the fact that in the absence of
restrictions Soviet political leadership was unable to counter the pressure
from its own defense industry that insisted on keeping up with the U.S. effort
and came up with its own large-scale SDI-type program. The Soviet Union was
fairly close to deployment of a number of prototype systems and the prospect of
the industry proceeding with deployment of some of its systems was very real.
Moreover, the political leadership did not have confidence in its ability to control
or influence this process. At the same time, the experience that the Soviet
Union had at the time with complex technical systems, military and civilian
alike, had demonstrated the uncertainties and dangers associated with them.
Understanding of these dangers was one of the reasons the Soviet Union was
consistent in its effort to curb the U.S. missile defense. It was directed
against the Soviet program as much as it was directed against SDI.

The issue of the Soviet own program that was produced in
response to SDI brings a question of whether the burden that it imposed on the
Soviet economy was a factor in the decision of the Soviet leadership to
initiate reforms or even in accelerating the demise of the Soviet Union. The
answer to this question is most certainly negative. While the package of
anti-SDI programs was supposed to be a massive effort, comparable in scale to
its U.S. counterpart, very few of these projects were actually new. The most
expensive programs, such as the Moscow missile defense system or the
"Energiya-Buran" heavy launcher, or the second-tier programs like the "Skif"
space-based laser, existed long before SDI. When they became part of the "D-20"
or "SK-1000" programs, they did not require any additional commitment of
resources. Most of the projects included in the package never went beyond paper
research and those that did were among the least expensive ones. Overall, while
the military spending was certainly putting a heavy burden on the Soviet
economy, there is no evidence that SDI or the Soviet response to it increased
that burden in any substantial way.[89]
Documents show that the issues of effectiveness of the military programs or shifting
resources to the civilian sector had not became prominent in the internal
discussions until about 1988, when the key decisions about SDI and the response
programs had already been made.[90]

The history of the Soviet response to SDI presents an
opportunity to test another argument, that suggests that a program like this
can work to dissuade an adversary. At the time of the discussion about the
Strategic Defense Initiative, one of the arguments in support of the program
that were advanced by the U.S. administration was that the missile defense
system would eventually devalue Soviet Union's investment in large ICBMs, which
constituted the backbone of the Soviet strategic forces. According to this
logic, the very prospect of being confronted with the defense would dissuade
the Soviet Union from undertaking an effort in building up its offensive
forces. SDI proponents tended to discount the effect that offensive
countermeasures may have on the effectiveness of defense systems, usually
pointing out at the tradeoffs in performance that the offense would have to make
to penetrate defenses.[91]

The evolution of the Soviet programs in the 1980s strongly
suggests that not only dissuasion did not work, but also that measures that
would be considered as advancing this kind of policy had exactly the opposite
effect. Far from being dissuaded from investing into its ballistic missiles,
the Soviet Union launched several development programs that were aimed at giving
them the capability to defeat defenses. There were, indeed, tradeoffs in
performance, but they were so insignificant that they had virtually no effect on
these programs. Neither did dissuasion work in a broader sense, failing to prevent
the Soviet Union from developing a set of measures aimed to counter the missile
defense deployment. The Soviet Union fairly quickly abandoned the attempts to
replicate the U.S. program and moved to the area of its "core competency", coming
up with simple and cheap anti-satellite systems to keep the space-based
components of the defense in danger.

Finally, the evolution of the Soviet attitudes toward SDI
suggests that the main factor that contributed to the ending the confrontation
of the Cold War was the willingness of the United States and the Soviet Union
to engage in a dialogue on reduction of their nuclear forces. The only result
that the SDI program was able to achieve in the context of confrontation was to
embolden those in the Soviet Union who defined security in confrontational
terms and benefited from this kind of understanding. As the evidence clearly
demonstrates, the Soviet defense industry had successfully managed to mount a
response to the U.S. program, even after it was largely deprived of political
attention and resources. Had the United States and the Soviet Union failed to
begin practical steps toward disarmament they would have found themselves in a
new round of arms race, regardless of whether or not the SDI technologies lived
up to the early expectations. Economic constraints and technological realities would
have scaled back the initial ambitious plans, as they in fact did, but the
systems that the Soviet Union would have deployed would still make the strategic
nuclear balance less stable than before. The dynamics of this process indicates
that it is unlikely that the Soviet political leadership would have been able
to contain this process even if it put an additional pressure on the economy
and the society in general.

The dialogue with the United States, as difficult as it
often was, provided the Soviet Union an opportunity to gradually move away from
the confrontational understanding of its security. It did so by empowering and
encouraging the institutions of the Soviet society that did not see
confrontation as their inherent interest. Eventually they were able to create a
framework that defined security in the terms that shifted emphasis toward
cooperation, even though they still operated by categories of strategic balance
and deterrence and stayed within the bounds of traditional arms control. The issues
associated with SDI presented a very serious challenge to this effort, but in
the end they had been successfully accommodated into this new framework as
well.
